Sump drain plug 320/04013 JCB Dieselmax, genuine

For the JCB Dieselmax 444 engine: sump drain plug 320/04013, a genuine JCB part.

The plug thread must match the sump thread; a different plug ruins it. Overtightening damages the sump thread, so keep to the specified torque. The plug is steel with a hex head; the washer underneath does the sealing. The plug sits at the lowest point of the sump.
